Visit https://developers.google.com/mobile/add and try to fill "Android package name". In some cases it can write error: "Invalid Android package name".

In https://developer.android.com/studio/build/application-id.html it is written:

And although the application ID looks like a traditional Java package name, the naming rules for the application ID are a bit more restrictive:

• It must have at least two segments (one or more dots).
• Each segment must start with a letter.
• All characters must be alphanumeric or an underscore [a-zA-Z0-9_].

So, "0com.example.app" and "com.1example.app" are errors.
